Tjernlund XchangeR Reversible Ventilation Fan

Many homes have damp basements that are stale musty or smelly because of seasonal water issues, sump pits, floor drains or general lack of air exchange. The XCHANGER Basement Fan is the economical and simple way to automatically ventilate your basement to eliminate basement odors and reduce humidity.

Easily flip ONE or BOTH fans to have them:

  • Exhaust musty air or air contaminated by wood off-gassing or radon
  • Supply fresh make up air in tight homes or for stoves and fireplaces
  • Position one fan in each direction for balanced fresh air exchange
